[PATCH 2/2] rebase: give a better error message for bogus branch

From: Jeff King <peff@peff.net>

When you give a non-existent branch to git-rebase, it spits out the usage. This can be confusing, since you may understand the usage just fine, but simply have made a mistake in the branch name.

Before:

  $ git rebase origin bogus
  Usage: git rebase ...

After:

  $ git rebase origin bogus
  fatal: no such branch: bogus
  Usage: git rebase ...
